LOCOMOTIVE.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed February 11, 1910. Serial No. 543.367.

To all 'whom it may concern.'

Be it known that I, SA MUEL M. VAUCLAIN, a citizen of -the United States, residing in Philadelphia, Pennsylvania., have invented certain .Improvements in Locomotives, of which the following is a specification.

The main object of my invention is -to make the-parts separate so that they can be more readily handled and can be easily repaired when necessary.

A further object of the invention is to make the frame of steel and the saddle preferably of cast iron; the cylinder castings being made separate and bolted to the steel frame, making a very substantial structure.

In the accompanyin drawings Figure 1, is a longitudinal sectional View on the line 1--l, Fig. 2, of sutlicient of the front end of a locomotive to illustrate my invention; Fig. 2, is a transverse sectional View on the line tional view on the line 3 3, Figl, illustrating a modified arrangement of the ports; Fig. 4, is a transverse sectional view on the line 4 4, Fig. 3; Fig. 5, is a longitudinal vsectional view on the line 5-,5, Fig. 6, showing my invention as applied to a piston valve engine; and Fig. 6, is' 'a transverse sectional 4view on the line 6 6, Fig. 5.

In the drawings, Figs. 1 to 4 inclusive, show the invention as applied to a locomotive having ordinary slide valves.

Referring in the first instance to- Figs. 1.

and 2, A is the front frame of a locomotive. This frame is preferably madeof steel and has extensions a proJecting rearwardly, which are bolted to the side frames of the locomotive. C is the bumper frame secured to the forward end of the front frame A. D, D, are cylinders secured to each side of the frame A, as clearly shown in Fi 2. B is the saddle which is mounted directly upon the front frame A and secured thereto by bolts or other fastenings. This saddle suports the forward end of the boiler and has, in the present instance, a central exhaust assage b and lateral steam passages b'.

hese steam passages connect, through pipes steam passages in the cylinder castings D, and the exhaust passage b communicates,

` in the cylinder castings. d, d are the valve seats, in the present instance arranged for ,the reception of the ordinary slide valves,Y

b2 shown by dotted lines, with the.

and the valve chestsv are mounted upon the cylinder castings. These partshave been omitted as they form no part of the present invention.

I` preferably make thefront frame A of d cast steel and use ribs a to strengthen the casting, and, in the present instance, as shown in Figs. 1 and 2, the steam connections between the cylinders and the saddle are located outside of the frame. The saddle itself I preferably make of cast iron', and

In Figs` 3 and 4, I have shown amodifi? cation of the invention which is also applied to slide valve locomotives, and in' this modification the exhaust passa-gesti2 ofthe cylinders D communicate with' passages f in the front frame A',and these passages in turn communicate with a central exhaust passage b4 inthe saddle., The steam inlet passaees are the same as in Figs. 1 and 2. In Figs. 5 andv, I have shown m invention as applied to locomotives provi edwith piston valves. In this construction the valve chambers'D form an integral part of the cylinder casting Dfand 'the steam passages d3 of the valve chambers communicate through pi es d" wit-hf.A the steam passages b' of the saddle castings, andthe central exhaust passages?) of the saddle castings B communicate with `the exhaust passages dof the valve chambers throughpipes g, as

shown in Fig.- 5.

struction there are no passages frame. f

I claim In this 'partleular con- 1. The combination of a front frame of a y i the front frame and supporting the forward .Y 11o end-of the boiler.l g

`this saddle may bc reinforced with ribs, if-

in the front 2. The combination in a locomotive, of a front having rearwardly extending 'arms attached to the side frames of the locomotive, cylinder castings mounted on each 5 sideiof thesaid frame, steam passages in the N x a .saddle cast' directly u n'the front frame an secured thereto, sai saddle being shaped to sup rt the forward end of the boiler and having steam inlet land exhaust 'passages said cylinder therein with the passages 1n the clnders, f

3. e 'combination in a locomotive, of a front frame made of cast steel and having exhausty passages therein vopenat each side and connected at their utgper ends, cylinder castings-on eich leide -of e front frame, the

exhaust paages of the said cylinder castings communicating with the passages of the frontr frame, and a cast lron saddle mounted upon and secured to the front e WM. A, AUSTIN, Hanny Somma.
